A rugged, top quality bias tee / DC power injector, this handy device enables you to inject the DC power required by your satellite LNB into the coax feeder cable.

It has three 'F' type female connectors:

Rx - connect your receiver here e.g. an RTL-SDR. DC voltage is blocked from reaching this socket.

DC - connect to the required DC power supply. Around 12V or 18V depending on which polarisation signals you want the LNB to receive.

LNB - connect the cable from your LNB here e.g. a Bullseye. DC power is provided for the LNB on this socket.

Important:

1. Be careful to connect each socket correctly. Connecting your receiver to the LNB socket with DC power applied could cause serious damage.

2. It is very easy to accidentally short circuit connections momentarily when connecting and disconnecting 'F' type plugs. Turn off the power when doing so and have short circuit protection in line with the DC supply.
